Application filed February 4,1907.' Serial No. 355,768.

To all whom it may concern:

Be it -known that I, MONROE W. GARRoLna citi-i zen of the United States, residing at Beaumont, in the county of 'Jefferson and State of Texas, have invented certain new and useful Improvements in Well-Bailing Apparatus, of which the following is a specification.

My invention relates to well bailing apparatus and to that class in which a valve bucket is raisedand lowered within the tube of the well and discharges its contents above a gate in said tube, consisting of certain features of construction fully set forth hereinafter and illustrated in the accompanying drawing which shows the said apparatus in sectional elevation in connection with the usual derrick and operating means.

The well tube A is provided with a gate E and with a port t above the gate, and with an extension l0 above theport. Abailing bucket B slides in the tube and is open at the bottom with a valve seat to which is adapted a valve P, and the stem or spindlev 2 of said valve extends through a guiding spider 3 and through the cap 4 of the bucket, and has at the upper end a contact piece J which slides with the stem and is heldagainst a stop or nut 5 bya spring 6. The valve P has ports 8 closed by a valve -V.

Within the bucket slides a piston() suitablypacked and connected with two piston rods 7, 7, which constitute practically part of the iiexible suspensory of the bucket which is operated to carry the bucket up and down within the well tube. When the bucket is at the bottom of the well, the upward movement of [the suspensory carries the pistonv upward in the bucket, the valves V opening to permit the liquid contents of the well to pass into the bucket until the piston reaches its upper position, the spring 6 lifting the valve P and closing it, and the bucket being then carried upward until it is above the gate E which closes as hereinafter set forth. As the bucket reaches its upper position the Contact piece J is brought against a suitable stop device, as forA instance, a cross head K, when the bucket will continue to rise, but the contact piece will be arrested together with the valve P so that the bucket is lifted above the valve and the contents are discharged into the extension l0 of the well tube and pass out through the port t.

If the cross head was secured immovably in place the shock of the sudden arrest of the bucket might prove detrimental, and I, therefore, suitably weight the cross head and permit it to have a limitedpmovement upward and downward. Thus as shown a head or weight W is connected with the cross head and slides upon the extension 10, the downward movement being limited by a stop arshoulder 12, and I furthermake use of this arrangement as a means of securing power to operate the gate E. To this end I connect with the head W any suitable form of air compressor, the same being shown as consisting of two cylinders G, G, provided each with reverse pistons 14 secured to the rods l5 suspended from the cross head K, and each cylinder communicates with a channel Y in the head W which through a conduit 17 supplies air to a motor D of any suitable construction connected to operate the gate E. As shown the motor has a cylinder 18 provided with a piston 19 connected with the gate, and having a rod 2() which extends through a packing box in the head of the cylinder and is connected to a Weight 2l by a cord 22 passing over a suitable guide pulley 23. Each cylinder` G has near the lower end a port w so that when the head W makes contact with the stop 12 the pistons may descend in the cylinders, the air escaping until the pistons pass the port w when the air in the lower part of each cylinder will constitute a cushion to prevent too sudden a contact withl the cross head K, and the contact piece J with the head of the bucket.

-To guard the valve P against contact with liners or strainers in the well and also avoid the shock which would result from bringing the fiat bottom of the `valve against the surface of the liquid in the well il `provide a guard inthe shape of an inverted cone 24 at the'bottom of the valve P, `which cone is perforated to permit the liquid to pass readily to the ports 8, and further to act as a strainer to prevent the said ports from being obstructed by the materials.

.The flexible suspensory of the bucket passes over a suitable guide pulley F, and to permit the latter to swing to any desired position without effecting the vertical position of the suspensory coinciding with the axis of the bucket I support the guide pulley F by a bracket I having a pivot 2G in line with the axis of the bucket and constructed to support the shaft of the pulley at one side so that the said line will be tangential to the periphery of the pulley,

the pivot 26 turning in a suitable bearing 27 at the head of the derrick L.

I do not claim herein any of the novel features illustrated and described in this application and also disclosed in my prior application, Serial No. 270,039.

Without limiting myself to the construction shown, I claim:

1. The combination with a well tube and its gate and port t and with a bucket and means for moving it in said tube, of a motor connected to operate the gate, and means whereby the motor is put in operation as the bucket rises above the gate.

2. The combination with a well tube, of a gate for closing` the same transversely, an extension above the gate provided with a port, a bucket provided with valves movable within the tube, a motor having a piston connected with the gate, and means for directing the motor fluid to the motor as the bucket is carried above the gate.

3. The combination with a well tube, of a gate for closing the same transversely, an extension above the gate propensory arranged to engage the cross'head as the bucket vided with a port, a bucket provided with valves movable Within the tube, a motor having a piston connected with the gate to move the gate in one direction, and a Weight for moving the gate in the other direction.

4. The combination with a Well tube, of a gate for closing the same transversely, an extension above the gate provided with a port, a bucket provided with valves, movable within the tube, a motor having a piston connected with the gate, and an air compressor for directing the motor fluid to the motor as the bucket is carried above the gate.

5. The combination with a Well tube, of a gate for closing the same transversely, an extension above the gate provided with a port, a bucket provided with valves movable within the tube, a motor having a piston connected with the gate, and air cylinders provided with pistons connected to move with the bucket as it passes above the gate, and means for conducting the air from said cylinders to the motor, y
